Title: Nozzle for gas turbine
Inventor: KAGOHARA HIROMI
IPC: F02C7/00
Filed: 1979-09-05
Abstract: PURPOSE: To improve a cast gas-turbine nozzle in strength and thermal fatigue by making it contain at least one of Hf, Ta and Zr as its constituent.  
     CONSTITUTION: The gas-turbine nozzle is made of an Ni-group cast alloy which contains 0.2W1wt% C, 18W45wt% Cr, 5W20wt% W and MO (at least one of them), and 0.2W0.8wt% Ta, Hf and Zr (at least one of them) and whose remainder constituent is Ni. The constituents, Ta, Hf and Zr, deposit as MC type secondary carbide. In other words, the constituents uniformly disperse and deposit in grains as carbides, so that they prevent carbide from depositing partially in the vicinity of the grain boundary. This permits the cast alloy to be improved in strength and thermal fatigue. Consequently, the nozzle can be improved in high-temperature corrosion resistance and high-temperature ductility.

Title: Continuous inspection for inclusion of thin steel hoop
Inventor: KAWAMURA KOICHI
IPC: G01N29/04
Filed: 1985-05-28
Abstract: PURPOSE:To achieve a simpler and smaller inspector, by making an ultrasonic beam emitted from an ultrasonic probe hit material to be detected vertically to detect inclusion of the material being detected from the attenuation of the bottom reflected wave from the back thereof. CONSTITUTION:A water jet nozzle 3-1 containing a focus type ultrasonic probe 2 and another one 3-2 without the probe 2 are arranged at the position facing each other to sandwich a thin steel hoop 1 as material to be detected. When an ultrasonic beam 4 is emitted from the probe to hit the surface of the steel hoop 1 vertically through a water column of a water jet, it is mostly reflected to be a surface echo S while a part thereof is transmitted through the thin steel hoop 1 and reflected on inclusion 6 and the bottom to be defect echoes F1-F3 and bottom echoes B1-Bn. Thus, detection can be done accurately and easily with a simple construction even when the inclusion 6 in the thin steel hoop 1 is very minute.

IPC: H01M10/05
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To improve the electrolyte leakage resisting performance of a battery provided with a crimp type sealing part and thereby to prevent the damage of the battery and an electric circuit due to electrolyte leakage by using a polyamide-amine-based organic agent, and by closing a gap between a metal battery case and a resin sealing plate or a resin gasket. SOLUTION: This nonaqueous solvent-based battery not causing electrolyte leakage, for instance, a nonaqueous solvent-based elliptical battery can be realized by closing a gap between a metal battery case 1 and a resin sealing plate 2 by using a polyamideamine-based organic agent having flowability, for example, fatty acid polyamicieamine or epoxy adduct polyamide as a sealant 3. When a nonaqueous solvent is used as an electrolyte, the sealant 3 is not dissolved in a small quantity of the electrolyte, and the sealant 3 swells and solidifies only on the innermost side of the case of the crimp type sealing part, that is, only at a position where the sealant 3 abuts on the nonaqueous solvent that is a dissolving solation, and its flowability can be kept inside the sealing part, so that an effect on the prevention of the electrolyte leakage is further enhanced.

Title: Electric power cable and manufacture thereof
Inventor: KAJIKI ISAMU
IPC: H01B7/30
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To provide easy manufacture for an electric power cable enabling easy connection and having superior effects for reducing a conductor loss, also manufacture for an electric power cable having an element wire insulated conductor. SOLUTION: In an electric power cable having a twisted wire conductor 1 formed by twisting plural element wires 2, an oxidizer forming oxidized films on the surfaces of the element wires 2, for example 2,5-dimethyl-2,5-hexyne diol, is contained in a coating 5 and/or intervening layers 4 contacted with the twisted wire conductor 1, to form oxidized films on the surfaces of the element wires 2 through heat, when the cable is energized. Thereby, it is not necessary to rip the films off when the cable is connected before it is used, which improves the working property of connecting, and when the cable is used, the oxidized films formed on the surfaces of the element wires 2 reduce the conductor loss.

Title: Date recording/reproducing apparatus
Inventor: SHIRAI KEN
IPC: G11B7/0033
Filed: 1992-05-06
Abstract: PURPOSE:To adequately change characteristic data by providing an accumulating area of the past history of characteristic data proper to the apparatus. CONSTITUTION:When a read signal from an optical card is to be binarized, the optimum value for the threshold level of the apparatus has been stored in an nonvolatile memory 19 beforehand at the adjusting time. A CPU 25 reads the optimum value of the threshold level from the memory 19 at the initialization, and inputs to a D/A converter 23. The output signal of an optical head 11 is compared with the read signal processed in a processing circuit 21 at a comparator 22, thereby completing the binarization of the read signal. When an optical card of different characteristics is to be used, the binarization may not be properly conducted because of tone difference of the threshold level. In that case, the number of errors in the data is increased and the reproduced data cannot be obtained at the worst. When correction unattainable errors are frequently brought about, a host computer 20 issues a re-determination command to make a controlling part 18 read, so that the processed read signal is converted by an A/D converter 24 and, the CPU 25 processes in a predetermined algorithm.
